**1. Introduction**

The pandemic has highlighted the importance of responsible use of resources in all sectors. The production sector is no exception. COVID-19 has given a push to transfer the circular paradigm from the economy to politics, precisely because the pandemic has planetary extension and repercussions. The key principle of the circular economy is the adaptation of economic cycles to natural cycles. A new paradigm is proposed as an innovative and advanced solution to combine growth in consumption and demand for goods with environmental sustainability [1]. This means rethinking the way in which we use matter and energy from design to production, from consumption to the management of the so-called "waste". In this context, with reference to the concept of waste, it would be desirable to speak of a "waste resource", thus overturning the very meaning of the term [2]. Today, it is quite clear that circular solutions will not be able to spread without the support

of digital technologies and infrastructures, within an extremely broad reference perimeter: transport, ports, digital infrastructures, energy, and electricity networks [3]. Digital transformation and sustainability should provide for interaction and integration between new physical and digital technologies or artificial intelligence, internet of things, augmented reality, additive manufacturing, both on the network side and on the digitalization of processes [4]. Positive repercussions of the sustainable transition on the economy are realistically achievable only on the condition of having facilities capable of allowing the exchange of resource flows through transcontinental infrastructures. A scenario that can only be obtained under the condition of a colossal exchange of information (big data) that will make it possible to meet the needs and demand for the well-being of a world population which, from 1970 to 2017, has increased by 2 times and world consumption of materials increased by 4 times with all the consequent negative effects in terms, for example, of waste production [5]. However, there has been talking of digitalization of infrastructures since the end of the nineties, but today we are quite far from the minimum goal of digitizing the backbones and essential resources of our planet [6]. The question is: how to give a metric, a dimension, a "measurability" of the quantities that can lead us to sustainability? Today, technology could help achieve this goal; for example, thanks to the immense computing capabilities of a quantum computer (quantum computing from IBM and Google are already available today for various simulations) or the evolution of deep learning. But all this may only be possible if the data is available. The key to building economic and social resilience, therefore, lies in digitization, which is the dominant element around which the collective future takes shape [7]. Thus, what are the challenges for achieving the paradigms of sustainability and digitization in this new era? And what are the tools for a "digicircular" transformation? The aim of this chapter is to investigate these issues. To this end, it should be noted that, in this chapter, our aim is not to present an analysis of literature in the classical sense but rather political and social reflections.

The rest of the chapter is organized as follows: Section 2 intends to analyze the link between sustainability, digitalization from a product life cycle perspective; Section 3 outlines how to design a "digicircular" future; Section 4 tries to summarize some challenges for digitalization and sustainability. Finally, in Section 5 the main conclusions of the study are outlined.

## **2. Sustainable sovereignty: condition for digital sovereignty**

Digitization and sustainability are among the most discussed topics in recent years and their simultaneous implementation will constitute the challenge and opportunity for the near future [8]. It is therefore essential to enhance the evolution over time of the links between these two and to understand if there are technologies that favor the creation of circular economies and, if so, what they are. As known the main technologies are: internet of things, cloud computing, augmented reality with artificial intelligence, additive manufacturing, horizontal and vertical integration, cybersecurity, autonomous robots, simulation/digital twin, and big data analytics [9]. From our point of view, it is interesting to analyze the link between sustainability, digitalization/technologies from a product life cycle perspective [10]. Thus, an investigation on Scopus, the largest abstract and citation database of peer-reviewed literature has been carried out in this research. The database was queried using the Boolean operators AND and OR as the following string shows: (TITLE-ABS-KEY (sustainability) AND TITLE-ABS-KEY (digitalization) OR TITLE-ABS-KEY (internet AND of AND things) OR TITLE-ABS-KEY (cloud AND computing) OR TITLE-ABS-KEY (artificial AND intelligence) OR TITLE-ABS-KEY (augmented AND

reality) OR TITLE-ABS-KEY (additive AND manufacturing) OR TITLE-ABS-KEY (horizontal AND vertical AND integration) OR TITLE-ABS-KEY (cybersecurity) OR TITLE-ABS-KEY (robot) OR TITLE-ABS-KEY (simulation) OR TITLE-ABS-KEY (big AND data) AND TITLE-ABS-KEY (product AND life AND cycle)). In detail, all the articles that had the string in the title, in the abstract, and in the keywords were selected. The search returned 384 documents. The 384 papers were analyzed not with the intent of developing a detailed literature review. Rather, the purpose of this investigation was to identify challenges and future trends with respect to two aspects, the most used keywords, and publication sources. But before analyzing the above features it is remarkable to note the distribution of documents over time. Documents are distributed from 1999 to 2021 (in progress), but obviously only in the last 5 years has there been an increase in the number of publications as shown in **Figure 1**.

To underestimate the interconnections and trends relating to the concepts of sustainability and digitization from a product life cycle perspective, has been used VOS viewer software [11]. In particular, co-occurrence analysis and bibliographic coupling were performed. Analysis of keyword co-occurrence is the bibliometric method used to map the research field. The process of creating keyword networks and clustering keywords is aimed at identifying the main research fields in the area of technologies (i.e., internet of things, big data analytics and, recently, also additive manufacturing) and environmental sustainability (see **Figure 2**).

In detail, it emerged that Internet of Things technologies are mainly used to extend the life cycle of the product but they prove to be a good solution also for the management of waste collection and recovery operations in the supply chain [12–14]. While, Big Data Analytics technologies are useful to use resources efficiently, to collect or manage data relating to the life cycle of products, and to develop new business models in a circular perspective. Artificial Intelligence can contribute to the implementation of a sustainable process in accelerating the development of products, components, and the choice of sustainable materials through assisted design processes that allow rapid prototyping and testing. It also favors the implementation of circular business models [15, 16]. Additive Manufacturing can incentivize sustainability thanks to the support it offers in terms of product life cycle management, recycling processes, and digitalization of production. In other words, a factory should be designed to be completely connected: from machinery to integrated processes, which will be combined with Artificial Intelligence algorithms [17, 18]. **Figure 3** shows a bibliographic

coupling analysis considering the sources. It emerges that the *Journal of Cleaner Production* is one of the most attractive scientific references for these issues. The result is not surprising because in the scientific community the journal is recognized as one of the best, interdisciplinary journals in which scientific works are encouraged that combine three key elements: reduction, environmental, and sustainability.

The analysis shows that there will be no emerging technology on the others, but an integration of technologies. A hybridization of digital technologies that will favor the transition towards sustainable production in view of product life cycle management is needed [1, 19, 20].
